The MTVR series of trucks are some of the best I've seen. Catepillar C-12 and an Allison 7 speed dual clutch auto, 6x6, Mud, Sand, and Snow modes, Tire inflation control, and will do highway speeds even under load. Its not as protected as the MRAP or other large infantry vehicles, but it comes in enough configurations to replace many of the older military work vehicles.
